 of marine beds destroyed the generally continental character of the 

 Miocene beds of the northern half of Europe. He repudiated the 

 idea of an immediate connexion between the elevation of the Alps 

 and the flow of the Severn, though such a general tilting of the 

 strata as that of which the last elevation of the Alps was one of 

 the principal results, produced its effects upon a wide area in Western 

 Europe. The volume of the rivers in former times had nothing to 

 do with his subject ; but the cutting back through escarpments was, 

 he thought, best explained in the manner he had suggested.
